I bought a few nice books for my library while in the UK.
This book, illustrated by Clarke Hutton. It was originally published in 1945, and I love the colours of the drawings.
The ultimate Peter Rabbit book was too big to scan properly, but it gives you an idea.
If you like Beatrix Potter, buy it!
And finally this one, all about houses in Britain.
It's a perfect inspiration for when I have to draw a cute house or cottage.
